clinical efficacy of two erythropoietin drug in participants with secondary anemia to chronic kidney disease.

Conditions: Chronic Kidney Disease; Anemia

Summary: this is a prospective, randomized, multicenter, parallel, placebo-controlled, phase iii study for evaluation of clinical efficacy and immunogenicity of drug eritromax® - (rhuepo blau farmacêutica s/a.) compared to eprex® (janssen-cilag rhuepo) for the treatment of patients with secondary anemia to chronic kidney disease (ckd), throughout the correction phase by assessing the change in hemoglobin levels.

this is a phase iii study, in which participants with secondary anemia to chronic kidney disease will receive two subcutaneous injection of 50 ui/kg of the investigational product (eritromax®) or eprex® per week. after four weeks of treatment, the dose of drugs will be change by clinical judged throughout study according to laboratory results. the evidence of efficacy will be evaluated by hemoglobin levels alteration throughout the correction phase (first four weeks). secondary efficacy and safety endpoints will be assessed by: maintenance of hemoglobin levels (baseline vs. end of treatment) over maintenance phase; dose of epo required during correction and maintenance phase; transfusion needs; report of adverse events (including type, frequency, intensity, serioussness, severity and relation to the investigation product) throughouht 12 months of follow-up. additionally, the immunological response of products over study will be evaluated by quantification of anti-erythropoietin every six months.
